Hi there. A small update:

necrolongplayer (0.0.3)

* folder view: added button for moving up/down in directory structure
* fixed: crash when replaced folder size is smaller than previous
* several fixes (eg orientation, still not perfect)

As there were no complaints about the bug (which was severe) i presume there are no other users beside me

Now the player is in extras-devel:
http://maemo.org/packages/view/necrolongplayer/

p.s.
Getting it there was a great pain in the arse! feck! I think it was not much what needed to be changed, but finding the right combination....(all tutorials were only close to the solution)
After setting up a linux vm just for this purpose (dont want to mess with my main system) changing something in control + rules & using custom build step & then upload to Maemo Extras Assistant finally did the trick.
Im still interested in using the publishing wizard from inside qtcreator (see above post). Is there someone who can negate its totally broken??
